You're encountering a known issue when trying to copy the General Channel folder from one Microsoft Team to another using SharePoint's "Copy Folder" action. The error:
"To update this folder, go to the channel in Microsoft Teams"
is specific to folders created by Teams channels, especially the General channel, which behaves differently from other standard or private channels.
Since copying the folder fails, you can:
This avoids the folder-level restrictions and preserves the content.
General_Copy.This keeps the structure clean and avoids conflicts with Teams-managed folders.
As per Microsoft guidance , folders created by Teams channels (especially General) should not be renamed or moved via SharePoint. Instead, manage them through Teams directly.
